To all whom amen {concern Be it known that I, Anvin G. .SANDVILG, a

citizen of the 'UnitedfStates, residinglat Grafton, in the countyof Walsh, State of North Dakota, ,have invented certain new and useful Improvements in 'Pitchforks; and I do hereby declare the following to be a full, clear, and exact description of the-jinvention, such as .will enable others skilled in the art to which it appertains to make and use the same. i s p I y qThis invention relates to improvements in pitch forks.

now 1n. general use.

:flhe principal object of the invention to provide a novel means for adjustably 'con necting. the tines of :the fork whereby the fwidthof said fork may be readilyregulated.

1 struction, and is cheapto manufacture.

iththese and other objects in View, theinvention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereto appended; it. being understood thatvarious changes in the form, proportion, .s ze' and nilnor detalls of construction wlthln the;

scope of the claims maybe resorted to without departing from the spirit or sacrificing any of the advantages of the nventiongl In the drawing: Figure 1 is a top plan 1 v fthat whenthe inner endsof the'levers 15 are,

view of a pitch fork constructed in accordance with my invention, the tines being shown in their normal positions, Fig. 2Jisa bottom plan view thereof, the tines being shown in their extended relation, Fig.3 is a detail sectional view taken on theline 3-.3

of Fig. 2,Fig. 4 is a detail sectional View taken on the line 4-4 of Fig. 2, Fig. 5 is a perspective view of the head, and Figl'iG is a detail cross sectional View taken on the line 6-6 of Fig. 2,.the tines beingshown in elevation.

Like reference numerals'designate corresponding parts in all the figures of the drawing.

Referring to the drawing, A designates a handle which is provided with a ferrule 5 at one end. Attached to this end of the handle is a head 13., Theresa]; comprises a UNI ED OFF rectangulartubefi which is formedwith a A central'ldependingf portion 7 from which 'rearwardly extends an attaching plate 8,

saidplate being formed with a longitudinal slot 9. Thisplate isisecured at its free end to'fthe handle A in spaced relationto the ferrule v,5.. Centrally projecting from the.

tube b above the attaching plate 8 is a pin 10 whichprojects into the ferruleend of the handle A, serves to properly support the head.

, rality of intermediate tines 1 1 andend tines,

12*12. ,The intermediate tines 11 are each formed at their inner ends with rectangular My invention furthercomprises a pin sleeves13Jadapted to slidev upon the tube 6.,

Projecting downwardly from the underface of each sleeve 13:is a pin 14, and fulcrumed upon each'pin is'a lever '15, the inner ends of the levers being arranged'in overlapping relation and disposed intermediate the handle A and the attaching plz ttev 8. A tightening bolt 16 passes through the slot 9. of the attaching plate 8 and. engages in suitable openings respectively,"fornied 'inthe overlapping ends of thelevers'15,and is adaptedv hold said levers inqa'ny adj ustedjposition along the sl0t19. The outer tines, 12 are each formed withlaterally extending 'angue lar arms 17, and these arms, are arranged to telescope within 1 the respective ends; of the end to a pin .18, andatits other end to the free end oftlie lever 15, as at 20."

From the foregoing, it will be observed secured to' the outerend of the slot 9, the tines 121will bedisposed in their normal or contracted position. When, however, the inner ends of the levers 15 are disposed within theinner end of theslot 9, the outer tines 12 will be shifted outwardly along the tube 6 by means of links 19, as will be readily understood. It will of course be under likewise be moved for a certain distance.

tube 6. "Projecting downwardlyTfrom" the "angle of each tine is a pivot pin 18. Links 00- 1919 are each. pivotallyconnected atone It will thus be observed that the width of.

the fork may be readily changed to suit Various needs thereof.

What is claimed is: v

1. In'a pitch-fork, the combination with a head, of outer tines connected to the ends of the head for adjustment therealong,

termediate tines slidableon the head,levers each fulcrumed intermediate its ends to a respective intermediate tine, links each piv otally connected at one end to the outer end ofa lever and at its other end'to a re: spective outer tine, and means for adjustably connecting the inner ends of the levers to the .head.

2. In a pitch fOlli, the combination Wltlla head having an attaching plate centrally extending therefrom and arranged at right angles thereto, of outer tinesconnected to the ends of the head for adjustment therealong, intermediate tines slidable on the head on eithervside of the plate, levers each fulcrumed intermediate its ends to a respective intermediate tine, links each pivotally con.-

nected at one end to the outer end of a lever and at its other end to a respective outer tine, and .means .for adj ustably connecting the inner ends of the levers'to the attaching "plate.

3. Ina pitch fork, the combination With a head having an attaching plate centrally extending therefrom and arranged at right angles thereto, of outer tines connected to l [the ends of the headfor adjustment therealong, intermediate tinesslidable on the head on either side of the plate, levers each fulcrumed intermediate its ends to :1 respective intermediate tine, links each pivotally connected at one'end to the outer end. of a lever and at its other end to a respective outer tine, and a pin andslot connection between the inner ends-of the levers and the 4. In a pitch fork, the combination with a tubular head of angularcross section,of

outer tines each having laterally extending angular armstelescoplcally arranged Within a respective end of the head, intermediate tines respectively formed at one end W1th a rectangular sleeve for sliding engagement with the head, levers each fulcrumed intermediate its ends to a respective intermediate tine, links each pivotally connected at one for sliding engagement with the head, levers eachfulcrumed lntermediate 1ts ends to'the sleeve of a respective intermediate tine,

links each pivotally connected at one end to the outer'end of a lever and at its other end to the angle of a respective outer tine, and a clamping means extending through the slot of the plate and engageable with the inner ends of the levers for adjustahly connectingthe inner ends of said levers along the plate.

In testimony whereof, I aflix my signature, in presence of tWO'WltHBSSGS.
